Essay on How The Middle Ages Earned Its Many Titles

The Middle Ages began around A.D. 500, which was after the western half of the Roman Empire collapsed. They lasted to about A.D.1400 and are referenced as a period of time that experienced violence by Barbaric invasion, feudalism, disease, and strong feelings for faith. The Dark Ages, the Age of Feudalism and the Age of Faith are all appropriate titles however the label that best fits is the Age of Faith because of the political, economic and social influence the church held. The middle ages are often identified as the Dark Age because of the Black Death, invasions by the Barbarians, and because of lack of enlightenment for the common people. A plague most likely originating from Asia spread throughout Europe. Towns and even large cities†¦show more content†¦(OI) Not everyone was able to become a part of the clergy so they were reliant on these people to share the word of God with them. The Dark Ages has negative impact because the increased reliance on the church gave them even more power, and this challenged Kings and created potential political tension. During the middle ages the lack of protection and a stable government after the Fall of Rome created the need for a new political system. Feudalism was the political system that emerged and shaped the lives of people socially and politically. Manors were small communities that were made up of a castle, church, village, and land for farming. The structured society provided a place and responsibility for everyone. The feudal obligations showed that in exchange for one thing they would be provided with something else. Serfs and peasants would work and produce goods for the rest of the manor and in return had their land and promised protection. The vassals would need to obtain land from the Lord and in return would provide the Lord with military service, loyalty, and ransom if asked for (Doc. 4). To make clear the vassal’s specific allegiance to their lord whom they owed in for exchange for their fief they would take the Homage Oath (Doc. 2). This interdependent system required everyone to do their part and it created social classes that they were born into. Their daily lives were centered on the manor and that was how it stayed until towns began toShow MoreRelatedRomeo And Juliet Film Analysis879 Words   |  4 Pageslovers and has become a major trope within popular culture, so much so that it has been adapted to screen several times within the last century.

The New Prime Minister Of Canada - 1648 Words

On November 4, 2015 the new Prime Minister of Canada, along with his new cabinet, was sworn into office by the Governor General. The day was marked by a heightened sense of hope and excitement across the country. However, more than being simply symbolic, November 4 was an opportunity for the new Prime Minister to show canadians his government is prepared to fulfill commitments made during the election campaign. Of many, the most notable of these commitments was to achieve gender parity in the cabinet. To the delight of many Canadians and, the world, Mr. Trudeau was able to deliver on his promise. As many praised the Prime Minister for his decision, an equal number (while not questioning the qualifications or merit of those woman appointed to power) were asking the question: â€Å"Is an affirmative action cabinet truly a meaningful (and effective) way to right the wrongs of the past and recognize the importance and significance of women in Canadian society?† Those who ask quest ions similar to the one above share the common view that the way in which Mr. Trudeau has decided to approach the barriers women face in society is not progressive, rather, is demeaning, sexist and ends up implying exactly what the core of gender discrimination is in the first place; the notion that one sex is superior to the other.

IB Biology Internal Assessment: Yeast Fermentation Rates Planning(a) Question- Growth: What is the effect on Yeast Growth/Expansion during fermentation when mixed in water of varying temperatures?

We will write a custom essay sample on Yeast Fermentation Rates or any similar topic only for you Order Now It is commonly used to rise bread, or to make alcohol, in a process known as Alcoholic Fermentation in which it releases oxygen. Through my research, I learned that during fermentation, the temperature is a very important factor in yeast expansion, as under 100 degrees, the yeast may not activate, while high temperatures will effectively kill your yeast, rendering it useless. My Lab Experiment served to test the effect of temperature on yeast expansion during fermentation. Presentation- Temperature |Repeat | |Volume Change | |90 | |1 | |0mL | | | | |2 | |0mL | | | | |3 | |0mL | | | | |4 | |N/A | | | | |5 | |N/A | | |100 | |1 | |30mL | | | | |2 | |0mL | | | | |3 | |N/A | | | | |4 | |N/A | | | | |5 | |N/A | | |110 | |1 | |10mL | | | | |2 | |0mL | | | | |3 | |N/A | | | | |4 | |N/A | | | | |5 | |N/A | | |120 | |1 | |50mL | | | | |2 | |0mL | | | | |3 | |N/A | | | | |4 | |N/A | | | |5 | |N/A | | |130 | |1 | |0mL | | | | |2 | |0mL | | | | |3 | |N/A | | | | |4 | |N/A | | | | |5 | |N/A | | | | | | | | | Yeast Expansion Conclusion and Evaluation- Conclusion- As is shown by my data, after the first trial at each temperature, the yeast refused to rise. This is due to temperatures effect on yeast, as a living thing. After completing the first five trials and ending my experiment for the day, I placed the jar of active dry yeast in the fridge where, due to prolonged exposure to such low temperatures, the whole jar died. After frustratingly watching the next seven trials yield no rise in the yeast, I came to the realization that the cold of the fridge killed my yeast. This was just as much a surprise (as the jar said â€Å"refrigerate after opening†), as it was an interesting basis for my lab. Because my Lab was about Temperature’s effect on yeast expansion and growth, this death provides a good conclusion, as it shows that prolonged exposure to extreme cold(around 58 Degrees F in my fridge), effectively kills the yeast, just as exposure to extreme heat does. At the 90 Degrees of trial 1, the yeast simply was not activated, but at 130 degrees, it also didn’t activate. Because temperatures below 130(save 90) activated it, I assumed that this was the temperature that kills yeast, just as 58 Degrees does. Limitations of experimental design- Many aspects of my project did not work very well and could have been improved in order to make for a better experimental design. For instance, instead of simply placing the yeast in water, I could have made dough, and placed it in the oven at different temperatures, making for a much more stable environment and temperature. Also, completing all 25 trials would have yielded better results as to what temperature truly leads to the greatest expansion by the yeast during fermentation. ———————– [pic] How to cite Yeast Fermentation Rates, Papers

Coach Carter Assignment free essay sample

Looking closely at his method of coaching, there are both positive and negative aspects that surround it. Firstly, his rule of ‘all students must be seated in front of the class’ is perceived as a positive aspect. In the movie, it was said that Richmond had a very low success rate. Only 50% of students graduate from Richmond, and the majority of those were girls. This shows that the other half either stay back, or don’t pursue a higher education. With this rule enforced among the players, this will enable them to focus more in class as they will be closer to the teacher allowing them to understand what is going on in class. This will ultimately benefit them as they will be able to graduate and not be part of the 50% who stay back. Carter also required that the players maintain an average of 2. 3. This can be seen as both a positive and negative aspect. We will write a custom essay sample on Coach Carter Assignment or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Carter made this rule because this is the average required for students to be admitted to college/university. In Carter’s eyes, these players are talented basketball players and if they are able to maintain that average, they will get certainly get into a college where they are offered a basketball scholarship. This shows the advantageous aspect of this rule. However, the negative aspect is that there are those who joined just to simply play basketball. As such, they will not like these rules. In the movie, it is seen that Richmond is a very violent area filled with gangs. If the players are not allowed to play basketball because they do not follow these sets of rules, they will not have a hobby and may potentially be involved in gangs. This is seen in the movie where the parents complained to Carter, stating that the only reason their son isn’t involved in gangs is that because they have a hobby such as basketball. One of the management theories seen by Coach Carter is the ‘Administrative Principles’ by Henri Fayol. This is seen through his applications of division of labour, discipline, and unity of direction. Division of Labour is seen where he decides who is the point guard for the team, and who should be the person who takes the three pointers. For example, Carter made Timo Cruz the person in charge of taking three point shots because that was his specialty. This coincides with one of the principles from the theory of ‘Scientific Management’ which says that managers should carefully select workers with the right abilities for the jobs. Discipline was evident during the court scene where a trial was held in regards to Carter cancelling Richmond’s basketball games because the players did not meet his expectations, i. e. GPA is lower than 2. 3. Carter said that if the students are unable to follow a simple contract that they agreed to, how would this make them be responsible people in the real word? As such, his use of making all members sticking to the agreements they signed taught them discipline. The principle of ‘Unity of direction’ was evident in the final basketball game. Carter would tell the team a certain plan, and all the players did what they had to do to execute the plan. A principle of ‘Bureaucratic Organization’, by Max Weber, was seen as well by Carter. Carter followed the principle of impersonality. The principle of impersonality states that the rules and procedures practiced should be the same for all. For example, when a member is late for practice, they are to do pushups and suicides etc. When his own son came late, he made his son do the same and did not excuse him just because of their father-son relationship. This shows that Carter is equitable towards all. In my opinion, Carter is a good manager because not only did he make Richmond one of the most successful basketball team but does things that benefits the students on the team as well. Firstly, is because of the expectations that he sets out for each student. In order to continue playing for the school basketball team, they must sign a contract promising to achieve basic academic standards. This makes him a good manager because not only does he want the team to win their basketball games, but he cares for each and every individual member by making sure that they have the marks required for further education. Secondly, is that he is not afraid to take action. Sometimes, when things go wrong in a team, the manager/coach just let it slide because he/her is afraid of ruining the relationship between them and the team. As seen in the movie, Carter announced a lockout for the Richmond basketball team when he notices that the some of the students did not meet the 2. 3 average. This means that they were not allowed to access the gym for practice, or participate in any games. The reason he did this is because again, he wants the students to put effort into school in hope of a better life portraying that he cares for students on the team. Lastly, is that he promotes a good sense of teamwork. This ties in with the last example about the lockout. There were people on the team who met the 2. 3 GPA but there were some who didn’t. Instead of just banning those who did not meet the standards, he banned the whole team from playing. He wanted every member to support one another and succeed as a whole. Overall, Carter is a great coach because not only did he turn Richmond into a successful basketball team, but cared for each and every member by ensuring that they have the marks needed for higher education etc. If I was the coach, I would mainly use principles from Henri Fayol and ‘The Hawthorne Studies and Human Relations’. Division of Labour, unity of direction, and equity would be found in my style of coaching. I would divide the work up by ability. For example, in basketball, if I was the coach I would make a person who is small but have good shooting skills be responsible for taking three point shots. By telling them that this is their job, this person would not drive into the key and go for a layup because they are small and would possibly be blocked. This job would be saved for a bigger person. As such, if each member played their assigned role, there would be no weakness as they will not conflict with other’s jobs that are not their forte. The idea of unity of direction where the leader makes a single plan and all members execute that plan is in my opinion, very effective. This is because I, as the coach, would want what is best for the team. With this mentality, I would devise a plan that is most effective. If the coach doesn’t come up with a plan, someone on the team might have their own ambitions, and do their own thing such as taking tricky shots to impress the crowd. This might result in a loss. I also believe in equity where managers should be kind and fair. This is because if coaches are nice to their players, this would achieve more productivity. The ‘Hawthorne Studies and Human Relations’ showed that people’s feelings, attitudes and relationships with coworkers affect their work and that those who are nicer to their employees will allow them to accomplish more work. As such, if I were a coach, I would use a mix of Henri Fayol and ‘The Hawthorne Studies and Human Relations’ theory.

Platos Ring Of Gyges Essays - Ancient Greek Philosophers, Platonism

Plato's Ring Of Gyges The Ring of Gyges The story of the Ring of Gyges is an excerpt from book two of Plato's The Republic, in which Glaucon disagrees with Socrates and insists that people act moral because they lack the power to behave otherwise. In an effort to support his claim, Glaucon recites the tale of Gyges. In this paper, I will include a brief history of Plato, a description of the Ring of Gyges, and discuss how the story may affect our present lives. Plato was born in 429 B.C. in Athens, Greece, to Ariston and Perictione. Plato's real name was Aristocles, and 'Plato' (meaning 'the broad') was a nickname given either from the width of his shoulders, or from the size of his forehead. When Plato was a young man he became a disciple of Socrates, learning the value of reason and philosophy. Plato was in military service from 409 B.C. to 404 B.C., but at this time he wanted to pursue politics rather than a military career. At the end of the war he joined the Oligarchy of the Thirty Tyrants, but their violent acts resulted in Plato leaving quickly. In 403 B.C. a restoration of democracy in Athens began, and Plato had great hopes of reentering politics. However, the execution of Socrates in 399 B.C. had an immense effect on Plato and he decided on having nothing further to do with politics in Athens. Plato left Athens after Socrates had been executed and traveled in Egypt, Sicily, and Italy. Upon his return to Athens, in about 387 B.C., Plato founded the Academy, an institution devoted to research and instruction in philosophy and science. Plato was disappointed with the ethics of those in public office (JOC 1). The Academy's primary goal was to educate citizens for statesmanship (Sahakian 35). Plato presided over his Academy in Athens until his death in 347 B.C. (JOC 1). The Ring of Gyges is a story written by Plato in an attempt to force the reader to evaluate his or her own sense of morality. In this story, Gyges worked as a shepherd for the king of Lydia. An earthquake opened up the ground where Gyges' flock was feeding. Inside this opening lay a bronze horse with doors. Inside these doors was a dead body with a golden ring. Gyges pulled the ring from the dead and climbed from the hole. He later joined his fellow shepherds to make a regular report to the king about his sheep. As he sat and toyed with his ring, Gyges noticed that when he turned the setting around on his finger he became invisible to all. He then became a messenger from the shepherds to the court; Gyges took his pleasure and seduced the queen. He later conspired with queen and killed the king, taking control of Lydia. After the story is told, Glaucon asks Socrates to imagine that two magic rings exist. A just individual has one ring, and an unjust person holds the other. Glaucon argues that no man could resist the temptation of taking what is not his, therefore the actions of the just would be as the actions of the unjust. This may affirm to be proof that a man is good, not willingly, but of necessity. If self-indulgence can be practiced without fear of punishment, then the tendency for being unjust will prevail (Jowett 257). What would one do if one possessed a magic ring? One could argue that there is a resemblance between Gyges and President Clinton. The President is a very skillful politician, a master of evasive talk. Plato states, A man who uses his power in the endless pursuit of the delights of the flesh possess the soul of a tyrant. Plato also understood that democracy is susceptible to a certain form of tyranny: the rule of a generous government, catering to the public's needs and wants in exchange for their freedom. Could one associate Plato's idea of a tyrant with the actions of President Clinton? The President has squeezed out of every tight spot in which he has landed. Clinton's cleverness may lead him to think he possesses a Gyges' ring of invincibility. He can allow his passions and sensual desires

Movie Critique essays Intense car chases, extraordinary fight scenes, a great story line. These are all components of a good movie. Warner Brothers executes these with pizzazz in the movie The Matrix: Reloaded by director Josh Oreck. The matrix is a science fiction movie and thus appeals to a very critical audience. It displays all the necessary components of camera arts and computer imaging. We have come along way from Thomas Edisons first film, Fred Otts Sneeze which used roles of celluloid film. The story of The Matrix is society in the future. We have developed A.I. (artificial intelligence) and it has gone beyond our control and in an attempt to terminate the problem we have fallen into a war. The real world is in ruin as a result of our futile attempts to stop the machines we have scorched the sky and the machines have destroyed our cities. The machines have managed to harvest and grow humans for our BTUs (body heat) they harness that to create electricity and thus have fueled their world. We live in incubators where the machines have created a virtual world for us, which they control via probes and fluid lines that they feed us through metal implants. The main metal implant is at the back of our heads where they tap into our consciousness, thus creating an alternate world. There is one human city left however, made by those minds that have been set free from the matrix and are of course unplugged, the city is Zion. The prophecy believed by most of the people is that the One lives in the matrix and can end the war. He lives in the matrix but can bend the rules of the construct of the matrix because it is a computer program it has rules. He can bend those rules at will and defeat the agents which are programs that work for the matrix keeping us slaves to the machines. In the first movie Morpheus (Lawrence Fishburne) sets the One free. ...

Retail strategy - Essay Example Further to him, these studies have noted some quite common traits among the existing entrepreneurs with respect to the need for complete achievement, the perceived locus of control and measure, are orientated toward initiative thinking and have a risk taking propensity in them. According to Beech, W (2001), an entrepreneur is driven by the need to create something new or build something tangible for others to follow. Also, entrepreneurs are described as human beings who are most of the times engaged in the creative destruction of products and services which exist. All in all, since new enterprises have low chances of success rates, an entrepreneur must also have considerable persistence if he/she is to attain the set goals. A crisis of management often arise when the entrepreneur fails to recognize that, running a large company which is stable is quite different from running a small growing company. This problem is often resolved by the entrepreneur leaving the organization and going to tart a new venture Another definition has it that, an entrepreneur is a person with the ability to see what others who came before missed. Further, he/she is a person who is able to make connections between things that others had not and are not capable of. He/she combines to work together to create that which had not existed before (Carey, C 2001). Often, the entrepreneur is not the one who actually creates the new goods or services, but he/she is the one who has the vision of how that idea can be transformed into reality for the benefit of everyone (Carey, C 2001). The entrepreneurs creativity is different from the creativity known. His/her creativity finds ways for the ideas which he/she has formulated to enter the market place as well as being of benefit to all of the society. Entrepreneurs in most cases reward those who came up with the new ideas in the first

However, being cognizant of this, the fast food outlets have become more sensitive to the nutritional needs of consumers and have included â€Å"health† fast foods in their menus and even going as far as regulating the amount of salt one can consume.

People with office jobs are more prone to this since they spend all day sitting down and eat packed sandwiches, fries and sodas, due to lack of physical activity, they quickly gain weight and in many cases, this portends health complications in posterity. Consumption of fast foods on a regular basis especially foods rich in simple sugars can lead to insulin resistance; this occurs when the pancreas is not transforming sugars into carbohydrates and energy. Insulin resistance is a precise to diabetes type 2 that occurs when the levels of blood sugar increases (Trembla). This often results to ill health, and one becomes prone to other health complications since diabetes weakens the body’s immunity. This is made worse if someone was already overweight, since it becomes hard for them to engage in

Analyze Abbott Laboratory's strategic response to compulsory licensing Article

Analyze Abbott Laboratory's strategic response to compulsory licensing - Article Example Abbott laboratory strategically responded to compulsory licensing by publicly announcing that it is going to withdraw the pending applications for selling current medicines in Thailand. Applications for seven medicines were withdrawn by Abbott. The medicines which Abbott withdrew their applications were Aluvia, Brufen, Abbotic, Clivarine, Humira, Tarka and Zemplar. It decided not to introduce new drugs in Thailand since the actions displayed by Thailand’s government did not respect patents. Several advantages and disadvantages can be associated with abbot laboratory’s strategic response to compulsory licensing (Baron, 2008). Strategic response employed by Abbot Laboratory proved to be advantageous since it created room for negotiation. Abbott’s strategic response made Thailand government to realize how important the organization is in pharmaceutical industry. Its strategic response made Thailand government to raise several complaints. This therefore made world health organization to intervene and discussed with Abbott on how to market its products in developing countries, including Thailand. Abbott’s strategic response also had some weaknesses. The response had a serious effect on patients. It deprived innocent individuals who seriously required lifesaving drugs. The strategic response also showed that Abbott laboratory lacks social responsibility and only mind about maximizing its profits. From the discussion, it is clear that Thailand easily issued compulsory licensing for Abbott laboratory product, causing the organization to angrily react. Abbott angrily reacted to the action by stopping introducing new medicines in Thailand. This strategic response created room for negotiation and caused serious effects on patients and company’s

Unilateral Peters Anomaly in a Nigerian Child

Unilateral Peters Anomaly in a Nigerian Child Case report Abstract 10-week-old female infant presented in our clinic in March, 2013 with history of small right globe since birth. There is associated history of whitish speck in the affected eye. The child is a product of term pregnancy which was uneventful. Mother denied any history of febrile illness during pregnancy. Nil history of maternal rashes, nil hearing or visual challenges, nil use of any drug apart from routine ante-natal haematinics. No history of use of traditional medicine in the course of her pregnancy. The patient is the second child of her parents. There is no similar occurrence in the other sibling or in any other member of the monogamous family. Ocular examination revealed right microphthalmos, microcornea and cornea opacity with pannus. The whole extent of the cornea was affected. An assessment of right Peters anomaly was made. The ocular ultrasound done revealed that the right globe measured 16.1mm in its AP diameter and the left globe measured 16.9 mm. There was cataract in the right eye and the anterior chamber was absent with adherence of the iris to the cornea. Patient was to be placed on cosmetic contact lens in future when she would be old enough t o manage it. Key words : Cornea opacity, microphthalmos, unilateral, Nigerian, child INTRODUCTION Peters anomaly is a form of congenital corneal opacity. It is associated with malformation of the anterior segment of the eye. 1 The aetiology of the condition is not clear. The most likely causes include genetic, infectious, traumatic and toxic factors. 1 Peters anomaly is a rare form of anterior segment dysgenesis in which abnormal cleavage of the anterior chamber occurs. The condition may involve the central or entire cornea. The leucoma is associated with irido- corneal adherences at the area of the leucoma. In the inherited form, mutations involve the PAX6 gene.2 Peters’ anomaly was described by Peters about one hundred years ago. 3It is a rare condition world wide, however the incidence rate is unknown. The condition does not have racial or sexual predilection. A study done by Bhandari et al. Showed equal distribution in both sexes. 4 There are two types of Peters anomaly based on the state of the lens namely type 1 and type 2. In type 1, the lens may or may not be cataractous but the lens does not adhere to the cornea. In type 2, the lens is cataractous and adheres to the cornea. 5 Type 1 is usually unilateral while type 2 is bilateral in 60% of cases. The cornea is usually clear at the periphery and vascularisation is not common however there may be sclerization of the limbus. Case History A 10-week-old female infant presented in our clinic in March,2013 with history of small right globe since birth. The mother noticed patient to have small right globe since few hours after birth. There is associated history of whitish speck in the affected eye. The child is a product of term pregnancy, which was uneventful. Mother denied any history of febrile illness during pregnancy. Nil history of maternal rashes, nil hearing or visual challenges, nil use of any drugs apart from routine ante-natal haematinics, nil ingestion of native concoction during pregnancy. She received routine antenatal Tetanous Toxoid vaccination. She neither smoked cigarette nor drank alcohol. She did not chew kola either. Child was delivered by spontaneous vagina delivery, vertex presentation. She cried spontaneously immediately after birth and the umbilical cord was cut using sterile cord scissors. She had received immunization according to National Programme on Immunization schedule. She had also been ac hieving all the normal developmental milestones. There is no history of any febrile illness since birth. She is the second child of her parents. There is no similar occurrence in the other sibling or in the family. Ocular examination revealed right microphthalmos, microcornea and cornea opacity with pannus. General and systemic examination did not reveal any other abnormality. An assessment of right Peter’s anomaly was made. The nature of this condition was explained to patient’s parents with counselling on how to raise the patient. Consent was obtained from the mother and clinical photograph of the condition was taken. The ocular ultrasonography done revealed that the right globe measured 16.1mm in its AP diameter and the left globe measured 16.9 mm. There was cataract in the right eye and the anterior chamber was absent. The left eye was sonographically normal. It is our belief that patient may benefit from the use of cosmetic contact lens in future. Discussion The early presentation of the patient is quite commendable. This may be related to the rarity of the ocular condition and the fact that the parents were enlightened. Most cases of Peters anomaly are sporadic however the inherited ones could be of autosomal recessive and dominant modes of inheritance. It is associated with abnormalities of chromosome 4. 6 We could not establish family history of similar presentation in the family of this patient. The other child of the parents was also said to be normal and in stable condition. Based on this fact, it is our considered opinion that the case may actually be a sporadic one. Peters anomaly is often an isolated ocular defect but there may be associated ocular and systemic anomalies. However further examination of the patient did not reveal any other systemic abnormality. This may be related to the fact that the condition was unilateral as bilateral Peters anomaly is more often associated with systemic anomalies. The globe was observed to be small and this was confirmed with the aid of ultrasonography. The associated anterior segment anomalies with Peters anomaly include glaucoma, anterior polar catarac t, cornea plana, sclerocornea, microphthalmos, colobomata as well as mesodermal dysgenesis of the anterior chamber angle and iris. 7 Peters anomaly may be associated with systemic anomalies like limb deformities, craniofacial anomalies, cleft lip and palate as well as genitourinary defects. 8-10 Treatment of Peters anomaly is challenging and unsatisfactory. The outcome of corneal transplantation is not rewarding due to post operative complications like graft failure, cataract, retinal detachment and glaucoma.11 Alternative treatment measures include rotation of corneal autograft, atropinisation of the pupil most especially if the visual axis is spared and optical iridectomy. The involvement of the whole extent of the cornea and the microphthalmic globe are associated with poor prognosis for visual recovery. Affectation of only one eye is also risk factor for amblyopia. The patient was not suitable for corneal grafting in view of the vascularisation of the cornea. Optical iridectomy or atropinisation was also not considered as the whole extent of the cornea was affected. In view of the poor prognosis coupled with the cosmetic challenge, the patient was to be placed on cosmetic contact lens when she is old enough to manage contact lens. Conclusion We conclude that prompt presentation and treatment of patients with Peters anomaly is desirable. There is need to create more awareness about the condition among health care providers and the populace in view of the fact that it is rare. Multidisciplinary approach should be adopted in the management of affected patients most especially those with associated systemic anomalies. Figure 1 : Child with right eye Peters anomaly

Abstraction called humanity c. Without regard to hygiene d. Hard- fought battle e. Fashion so distasteful complete indifference 9 One Sunday I entrained for Baling, a town in Vulcan which can well afford to hold two fiestas a year without a qualm. Kook the train partly because am prejudiced in favor of the government owned railroad, partly because I am allowed comparative comfort in a coach, and finally because trains sometimes leave and arrive according to schedule. In the coach I found a little world, a section of the abstraction called humanity homo we are supposed to love and live for. Had previously arranged to divide the idle hour or so between cultivating my neglected Christianity and smoothing out the rough edges of my nature with the aid of grateful sights without -? the rolling wheels, the flying huts and trees and light-green play seedlings and carbons along the way.Inertia, I suppose, and the sort of reality we moderns know ma ke falling in love with my immediate neighbors often a matter of severe strain and effort to me. Let me give a sketchy picture of the little world whose company Mans Koki shared in moments which soon passed away affecting most of us. First, there came to my notice three husky individuals who dusted their seats furiously with their handkerchiefs without regard to hygiene or the brotherhood of men. It gave me no little annoyance that on such a quiet morning the unpleasant aspects in other people's ways should claim my attention.Then there was a harmless-looking middle-aged man in green camas De chino with rolled sleeves who must have entered asleep. When I noticed him he was already snuggly entrenched in a corner seat, with his slipped feet comfortably planted on the opposite seat, all the while his head danced and dangled with the motion of the train. I could not, for the love of me, imagine how he would look if he were awake. A child of six in the next seat must have shared with me in speculating about the dreams of this sleeping man in green.Was he dreaming of the Second World War or the price of eggs? Had he any worries about the permanent dominion status or the final outcome of the struggles of the masses, or was it merely the arrangement of the scales on a fighting roaster's legs that brought that frown on his face? But the party that most engaged my attention was a family of eight composed of a short but efficient father, four very young children, mother, grandmother, and another woman who must have been the efficient father's sister.They distributed themselves on four benches – you know the kind of seats facing each other so that half the passengers travel backward. The more I looked at the short but young and efficient father the shorter his parts looked to me. His movements were fast and short, too. He removed his coat, folded it carefully and slung it on the back of his seat. Then he pulled out his wallet from the hip pocket and counted his mon ey while his wife and the rest of his group watched the ritual without a word.Then the short, young, and efficient father stood up and pulled out two nana leaf bundles from a bamboo basket and spread out both bundles on one bench and log luncheon was ready at ten o'clock. With the efficient father leading the charge, the children (except the baby in his grandmother's arms) began to dig away with little encouragement and aid from the elders. In a short while the skirmish was over, the enemy – shrimps, omelet, rice and tomato sauce – were routed out, save for a few shrimps and some rice left for the grandmother to handle in her own style later.Then came the water- fetching ritual. The father, with a glass in hand, led the march to the train acute, followed by three children whose faces still showed the marks of a hard-fought-battle. In passing between me and a person, then engaged in a casual conversation with me, the short but efficient father made a courteous gesture w hich is still good to see in these democratic days; he bent from the hips and, dropping both hands, made an opening in the air between my collector and me – a gesture which in unspoiled places means â€Å"Excuse Me. 10 In one of the stations where the train stopped, a bent old woman in black boarded the train. As it moved away, the old woman went about the coach, egging holding every prospective Samaritan by the arm, and stretching forth her gnarled hand in the familiar fashion So distasteful to me at that time. There is something in begging which destroys some fiber in most men. â€Å"Every time you drop a penny into a beggar's palm you help degrade a man and make it more difficult for him to rise with dignity..There was something in his beggar's eye which seemed to demand. â€Å"Now do your duty. † And did. Wily-nil I dropped a coin and thereby filled my life with repulsion. Is this Christianity? â€Å"Blessed are the poor But with what speed did that bent old Oma n cross the platform into the next coach! While thus engaged in unwholesome thought, felt myself jerked as the train made a curve to the right. The toddler of the family of eight lost his balance and caught the short but efficient father off-guard.In an instant all his efficiency was employed in collecting the shrieking toddler from under his seat. The child had, in no time, developed two elongated bumps on the head, upon which was applied a moist piece of cloth. There were no reproaches, no words spoken. The discipline in the family was remarkable, or was it because they considered the head as a minor anatomical appendage and was Hereford nor worth the fuss?Occasionally, when the child's crying rose above the din of the locomotive and the clinkers-clank of the wheels on the rails, the father would jog about a bit without blushing, look at the bumps on his child's head, shake his own, and move his lips saying, â€Å"Task, Task†. And nothing more. Fairly tired of assuming the minor responsibilities of my neighbors in this little world in motion, I looked into the distant horizon where the blue Cordilleras merged into the blue of the sky. There rested my thoughts upon the billowing silver and grey of the clouds, lightly remarking upon their being a Arial to us, although they may not know it.We each would mind our own business and suffer in silence for the littlest mistakes of others; laughing at their ways if we happened to be in a position to suspend our emotion and view the whole scene as a god would; or, we could weep for other men if we are the mood to shed copious tears over the whole tragic aspect of a world thrown out of joint. It is strange how human sympathy operates. We assume an attitude of complete indifference to utter strangers whom we have seen but not met. We claim that they are the hardest to fall in love with in the normal exercise of Christian charity.

How to use adverbs effectively - Emphasis

How to use adverbs effectively How to use adverbs effectively Adverbs convey information about how things happen, as well as when, where and to what extent. As the name suggests, they modify verbs but they can also modify adjectives, other adverbs and whole sentences, writes Cathy Relf. For example, in the sentence I need to see you urgently, the adverb urgently tells us about the verb need. But in Recently, weve been incurring a lot of delays, the adverb recently tells us about the whole sentence. However, informative and descriptive though adverbs certainly are, you should still use them with thought and moderation like all language. We tend to use a lot of fairly meaningless adverbs in conversation, to emphasise certain points, create rhythm and elicit empathy from the listener. But good, clear writing is more about communicating your meaning efficiently than banging your point home and that means only using adverbs that add genuine, useful information. Whenever possible, show, dont tell. Some adverbs are used so frequently in speech that they have become little more than verbal tics, and these are the ones you should be particularly suspicious of if they turn up in your writing. Below are five such words, each of which you should sternly interrogate before deciding whether to grant it a place in your final draft. Interestingly Interestingly, many writers like to introduce facts with the word interestingly. Interestingly, its often followed by something that isnt. If you have an interesting observation to share, let it speak for itself. And if you have a dull but necessary fact to convey, dont try to pep it up by calling it interesting. Youll lose your readers trust, as well as their attention. Heres what happened when we asked a group of editors on Twitter how they felt about sentences beginning with interestingly. Warning: its not pretty. Use it: in speeches, to create a moment of suspense before delivering a genuinely interesting point. Dont use it: to add interest where there is none. Significantly Much like interestingly, the thing about significantly is that most truly significant things can speak for themselves. Pinpoint the reason that you know your fact is significant do you have a statistic, for example? If so, can you use that instead, and let the reader be the judge of its significance? Instead of UK tourists pay significantly less for petrol, why not UK tourists pay 8.6 per cent less for petrol? Sometimes, however, youll have expertise that your reader isnt privy to, meaning you may be able to see significance where they cant. In this case, you can use the word to signal that a particular piece of information youre conveying is significant, and then follow up on how, or why, in the next sentence. Youre basically telling your reader hold on to this bit; youll understand why in a minute. Used like this, significantly can be a useful tool for creating reader engagement. Also, its worth noting that in statistics, significant has a specific meaning, with the significance level being the amount of evidence required to indicate that a result did not happen by chance. Too often, however, significant is simply used to create persuasive, attention-grabbing sentences that gloss over an absence of evidence. For example, see this headline from the Daily Mail: Less than 6 hours sleep significantly increases risk of a stroke even if you are fit and healthy. The article gives no information about the size of the increased risk it could be one per cent higher or 100 per cent higher. The reader is left none the wiser regarding the level of significance, and the same is probably true of the writer. Use it: to highlight facts that the reader may not immediately realise are significant. Dont use it: as a substitute for real information, or to make something seem more important than it is. Obviously Before you use obviously or clearly, ask yourself three things: firstly, if its obvious to everyone, do you need to make the point at all? Take, for example, the introductory sentence to this article in The Hindu: Quite obviously, the Reserve Bank of India, while reviewing the credit policy the mid-quarter review is scheduled for later on June 18 would take note of the recent developments affecting the economy. Once you unpick the sentence, it is obvious that a bank would consider economic developments when reviewing its credit policy. But did they need to say so? After all, if its obvious, is it news? Secondly, if its not obvious to your readers, how are they going to feel? Foolish, perhaps or, worse, patronised. And, thirdly, are you using obviously to discourage questioning? (After all, who would argue with something that has been declared universally obvious?) If so, take a moment to think about why youre using such a defensive tactic. It may be that there are holes in your own argument. Use it: as little as possible. Dont use it: if its likely that the information will not be obvious to some readers. Actually Actually is a useful discourse marker in speech. We use it for emphasis, surprise, contrast or correction (we thought it would be a good move, but it was actually a mistake, no, I live in Hove, actually, he was actually trying to take all the credit himself). However, in writing, actually should be used sparingly. If youre someone who writes like a demon in first drafts, itll often end up in there because your writing tumbles out structured like speech. Its actually a great way to get a first draft on to paper, but when you go back to edit it and actually look at the contribution each word is making, thats the time to question whether theyre actually adding any value or clarity. In the sentence above, wed delete the first two actuallys, but keep the third, which subtly intensifies the action of adding value. Use it: when it adds a useful hint of contrast or surprise to the sentence. Dont use it: just because you would when speaking. Literally This is, without doubt, the adverb with the most enemies. There are whole social media accounts devoted to pointing out inappropriate uses of literally. See @literallypolice on Twitter and The Literally Tsar on Facebook, if you dont believe us. The problem with literally is that it has developed a colloquial meaning that is the opposite of its literal, or dictionary, meaning. Often, when people say literally, they mean its opposite, figuratively. The footballer Jamie Redknapp has a particular fondness for the colloquial usage of the word, according to this Guardian article (he had to cut back inside on to his left, because he literally hasnt got a right foot). Despite all this fuss, only the most pedantic person would interrupt you in the middle of a story to question whether you were literally shaking like a leaf or literally chomping at the bit. But readers are pickier than listeners, and sentences such as these seem more incongruous in black and white. So, just to be completely literal about it, here are the definitions from Collins: Literal: in exact accordance with or limited to the primary or explicit meaning of a word or text. Figurative: of the nature of, resembling, or involving a figure of speech; not literal; metaphorical. In short, if it didnt really, literally happen, dont use literally. Use it: to describe things that really happened. Dont use it: for metaphors or exaggerated expressions. Want more advice on getting the most out of your business writing?

Free Essays on Noble Truths In Buddhism

The Buddha Shakyamuni was born in the 6th century BC in the area which is known today as Nepal. During his 80 year lifetime, he developed a philosophy which he claimed would lead its followers towards an enlightenment. Buddhism is commonly called a religion however; it differs from the usual definition of a religion in that it has no divine being and is based on logical reasoning and observation rather than spiritual faith. At the core of Buddhist philosophy is the Buddha's enumeration of Four Noble Truths: Dukkha (suffering), Samudaya (origin of suffering), Nirodha (cessation of suffering), and Magga(path to cessation of suffering). These Four Noble Truths form a logically consistent set of rules, or somewhat of a law, upon which the whole Buddhist religion is based. In order to fully understand the Four Noble Truths, it is necessary to investigate the Buddhist view of the individual and its makeup. In some respects, the manner in which Buddhism deals with the mind/body problem is much more advanced than most religious views, and closer to science's understanding of the mind and body. Rather than postulating the existence of an eternal soul with no physical manifestation, the Buddha taught that the person is really a collection of five skandhas or aggregates. These include rupa (matter), vedana (sensations), sanna (perceptions), samkhara (mental formations), and vijnana (consciousness). The aggregate of matter encompasses all tangible aspects of the world. The aggregate of sensations is akin to the process of sensory input; e.g., the activation of retinal cells in the eye. Vedana does not include the process of perception, however; the act of perceiving the senses, i.e., recognition of external sensations, is within the realm of the sanna. Buddha classified mental activities (samkhara), i.e., ideas and thoughts, as being disparate from the state of mental consciousness (vijnana). Consciousness, in the Buddhist view, is th...

The aggregate of matter encompasses all tangible aspects of the world. The aggregate of sensations is akin to the process of sensory input; e.g., the activation of retinal cells in the eye. Vedana does not include the process of perception, however; the act of perceiving the senses, i.e., recognition of external sensations, is within the realm of the sanna. Buddha classified mental activities (samkhara), i.e., ideas and thoughts, as being disparate from the state of mental consciousness (vijnana). Consciousness, in the Buddhist view, is th...

Different Styles in Movies Essay Example | Topics and Well Written Essays - 1250 words

Different Styles in Movies - Essay Example The essay "Different Styles in Movies" investigates such movie styles as Soviet Montage, Surrealism, German Expressionism and Impressionism. Equally important is the use of dream sequence to penetrate in to the layers of mind – conscious and subconscious. This style the focuses on the characters’ state of mind, impression of feelings and emotions rather than on the plot or drama of the story. Cinematography and editing are used to illustrate the state of mind, and dream sequences are used to reflect on the conscience. The wide use of impressionist methods is so palpable in Francis Ford Coppola’s film, that brought the internalized life of a detached expert ‘bugger’ Hary Caul on the scene. He would pass for a modern recluse, donned with headphones, holding an extended shot gun microphone. He probes into the private life of Ann and Mark. The film revealed contradictions in the inner and outer life of the protagonist through the subtle emotions on his f ace, physical movements, and also in his dialogue which intermittently gets spiced with silence. The camera opens with a bird’s-eye-view on the busy lunch time at Union Square in downtown San Francisco, with frames having visual details of pedestrians, workers on lunch break, and Christmas shoppers. There emerges the cadence of street musician’s concert which gets mingled with the gruff and hoarse noise produced by certain mechanical devices in the street. The inner conflicts of the character are illustrated through the varying degrees of music and cacophony.

Internet addiction Essay Example | Topics and Well Written Essays - 1000 words

Internet addiction - Essay Example People often tend to ask as to what internet addiction is. The focus of internet addiction can cause people to believe that they are being informed by the IAD, also known as internet addiction problem. This paper will look into the way in which internet manipulates people’s minds and distracts them, thus causing them to think about entirely different things and experience radical change in their priorities (Young, â€Å"Internet Addiction: Symptoms†). The solution to internet addiction is realization of addiction, time management, and increased family unions. Firstly, Internet addiction is a very nasty disorder that might even be more technical than the obsessive compulsive disorder (OCD) that most of the world is aware about. Just like OCD, the roots of internet addiction disorder are psychological and are triggered due to a nervous system that exists within the brain. What is shocking though, is the mere fact that internet addiction problem does not get as serious as OCD and is not fatal, physically, but it is fatal in the sense that a person loses his ability to grasp priorities and change from one situation to another in a smooth transition. A person having internet addiction will always have this time crunching feeling that he needs to work on something different, something more reproductive, on the internet. For example, a person who has an assignment to compete for his college will often try to complete the assignment because he feels responsible for it. However, if that student is addicted to internet, he will often get an urge t o check what is going on when it comes to his Facebook account, Twitter account, some other social media platform account and thus get distracted immediately (Young, â€Å"Internet addiction: the†). His conscience may have been about fulfilling his responsibility but his obsession with social media platforms drives him to ruin his own work himself. Moreover, it also becomes hard for the

Computer Forensics in Biology Research Paper Example | Topics and Well Written Essays - 1250 words

Computer Forensics in Biology - Research Paper Example Application A structured investigation is carried out to sort out what exactly happened to the computer, when it happened, how it happened, and who did it. This is exactly like solving a murder case and performing postmortem. The operator does not know that the evident information is transparently being created and stored by the computer’s operating system, which can only be extracted through computer forensics software tools and techniques. The crimes include misuse of computer systems, attack on computer systems, using a computer system to work against another system, failure of a computer system, and the like. Though, internet identity theft has made people uncertain about shopping and selling online, checking their bank statements online, visiting auction websites, or entering into business contracts or transactions; however, computer forensics has played its part in helping law enforcement agencies in gathering digital evidence and identifying stolen identities as well as the criminals involved. Computer forensics security solutions focus not only on recovery but also on prevention of security threats in order to provide security solutions that are quicker and cheaper than the conventional techniques. These solutions include intrusion detection system (IDS), internet security system, biometric security system, net privacy system, firewall set-ups, network disaster security system, identity theft prevention system, identity management security system, and so on (Vacca 146). Basic Scientific Principles Involved It is important for computer forensic investigators to follow a structured approach to solving computer and internet-based identity theft cases. Computer crime involving ID theft can be grouped as physical security breaches, personnel security breaches, communications and data security breaches, and operations security breaches. A detailed investigation of the case requires that every security breach is analyzed independently to get a more syst ematic approach towards case solving. The digital examination of ID theft cases requires great expertise at the investigator’s end. The evidence or data that is collected is the valuable asset and has to be dealt with sensitivity, as it will help in deciding the specifications of the crime. Digital data is so delicate that it can be altered with one mistaken tap on the keyboard or one inadvertent press of a key. The forensic investigator will have to use some offline techniques in addition to online techniques. Although offline techniques are not the responsibility of a forensic investigator, but of course, he can use them to help himself toward finding the evidential data. He will have to look for any counterfeit documents, fake checks and bogus bank statements in black and white, in addition to looking for digital evidence residing inside the fraudster’s computer system.  

Edgar Allan Poe Essay Example for Free

Edgar Allan Poe Essay The many different works of Edgar Allan Poe all aim to do one thing. Strike fear into the heart of the reader. Simple, yet effective, he expresses fear through these many different themes and motifs. At full length, Poe’s stories all acquire a distinct theme or motif that moves the story forward. Whether you know it or not, many of his stories rely on themes and motifs to make the story more appealing to the reader. Time, duality, and dreams all play key roles in Poe’s short stories. They descriptively provide all of the necessary information in order to produce the whole concept of fear. Without them, these stories wouldn’t push you to the edge of your seat, wondering what is going to happen next. Time plays a major role in providing the story with the crucial data it needs to make the story frightening and suspenseful. It presents the story with a visual that makes the mood of the story transition into a very adverse setting. Dusk is probably the most common time of day in many of Poe’s stories. He chooses dusk because, during that time of day, it is very difficult to see. For example, in â€Å"The Fall of the House of Usher† the narrator begins to describe how it is very difficult to see while he is making his way towards his child hood friend’s mansion. When choosing the time of day that produces little or no light, Poe tries to make the setting as dark as possible. Light represents happiness and positivity, so Poe tries to eliminate anything that represents prosperity. By assembling negative forces, the story will generate fear into the reader. In â€Å"The Tell-Tale Heart† the narrator stalks his pray for seven days, but on the eighth night the narrator commits the horrible deed. The number eight is used frequently with Poe and his stories; in this case, it represents what day the narrator will kill the old man. With â€Å"Masque of the Red Death†, time represents life. It represents life because once a person is infected with the red death; the infected person has only 30 minutes to live. The ebony clock also represents life, because after every hour the clock will ring, reminding the people that time is running out. This theme is very necessary for producing fear, because if Poe doesn’t clarify what time of day it is, the story loses suspense. So it’s apparent that time is a key necessity in conveying fear into readers. The narrator often produces dreams themselves. Frequently, it presents a distortion of reality for the narrator and the reader. Dreams in Poe’s stories draw the line between reality and fantasy. Many unexplainable things would occur and the narrator would instantly assume it would be his imagination or that he would be dreaming. Providing dreams will make the reader build curiosity into whether or not these bizarre things are real or just images of the narrators eccentric imagination. In â€Å"Masque of the Red Death†, a huge party is thrown, to isolate the people from the disease. In the party, the guests have a great time by dressing up and having a â€Å"perfect† time, until the ebony clock rings. Once the clock rings, the party guests snap back into reality for a short moment. For that short moment, the reader realizes the severity of the situation. That short moment of severity produces fear. During his trip to Rederick’s mansion in â€Å"The Fall of the House of Usher†, the narrator feels like the trip is a dream because the environment of the mansion is so surreal. Alcohol provides the narrator in â€Å"The Black Cat† with a distortion of reality, because after he hangs the black cat, he comes across a cat that is identical to the one he hangs after he leaves the bar. The narrator is completely shocked by the resemblance to his previous cat. This similarity conveys fear into the reader, because you can’t tell if it’s the same cat or a different one. The distortion of reality in dreams really help produce fear due to the doubtful events that keep occurring. These events help generate fear and build up the suspense in the reader for a few moments. Duality in the characters conveys the most fear towards the reader. By having a dual persona, the character is able to build up that suspense by having a â€Å"good† side and a â€Å"bad† side. As an animal lover, the narrator in â€Å"The Black Cat† would always love to take care of animals, until he becomes â€Å"consumed by the imp of the perverse† which exposes his negative side. This negativity leads him to killing his cat and his wife. The insanity of having a dual persona helps transmit true fear into the reader. As a young caretaker, the narrator in â€Å"The Tell-Tale Heart† has nothing against the old man he is looking after; the old man has done nothing wrong to deserve any negative treatment. During the day the narrator would go about his business taking care of the old man, until night came upon. At night, the narrator would be consumed by the old man’s eye. His â€Å"evil eye† leads the narrator to kill his wife and their pet. The duality in both of the these characters are very similar due to them being consumed by some object that leads them into killing their loved ones and pets. All of these themes help produce the backbone of Poe’s stories. Without these themes and motifs, these stories wouldn’t be as suspenseful as they are today. These stories rely on the descriptiveness and the intensity of these themes to carry the suspense and to convey fear into the readers. Today, as people still learn about Poe’s stories, they will still be able to consume the fear that they read due to these themes and motifs.

Literature review about data warehouse

Literature review about data warehouse CHAPTER 2 LITERATURE REVIEW 2.1 INTRODUCTION Chapter 2 provides literature review about data warehouse, OLAP MDDB and data mining concept. We reviewed concept, characteristics, design and implementation approach of each above mentioned technology to identify a suitable data warehouse framework. This framework will support integration of OLAP MDDB and data mining model. Section 2.2 discussed about the fundamental of data warehouse which includes data warehouse models and data processing techniques such as extract, transform and loading (ETL) processes. A comparative study was done on data warehouse models introduced by William Inmons (Inmon, 1999), Ralph Kimball (Kimball, 1996) and Matthias Nicola (Nicola, 2000) to identify suitable model, design and characteristics. Section 2.3 introduces about OLAP model and architecture. We also discussed concept of processing in OLAP based MDDB, MDDB schema design and implementation. Section 2.4 introduces data mining techniques, methods and processes for OLAP mining (OLAM) which is used to mine MDDB. Section 2.5 provides conclusion on literature review especially pointers on our decision to propose a new data warehouse model. Since we propose to use Microsoft  ® product to implement the propose model, we also discussed a product comparison to justify why Microsoft  ® product is selected. 2.2 DATA WAREHOUSE According to William Inmon, data warehouse is a subject-oriented, integrated, time-variant, and non-volatile collection of data in support of the managements decision-making process (Inmon, 1999). Data warehouse is a database containing data that usually represents the business history of an organization. This historical data is used for analysis that supports business decisions at many levels, from strategic planning to performance evaluation of a discrete organizational unit. It provides an effective integration of operational databases into an environment that enables strategic use of data (Zhou, Hull, King and Franchitti, 1995). These technologies include relational and MDDB management systems, client/server architecture, meta-data modelling and repositories, graphical user interface and much more (Hammer, Garcia-Molina, Labio, Widom, and Zhuge, 1995; Harinarayan, Rajaraman, and Ullman, 1996). The emergence of cross discipline domain such as knowledge management in finance, health and e-commerce have proved that vast amount of data need to be analysed. The evolution of data in data warehouse can provide multiple dataset dimensions to solve various problems. Thus, critical decision making process of this dataset needs suitable data warehouse model (Barquin and Edelstein, 1996). The main proponents of data warehouse are William Inmon (Inmon, 1999) and Ralph Kimball (Kimball, 1996). But they have different perspectives on data warehouse in term of design and architecture. Inmon (Inmon, 1999) defined data warehouse as a dependent data mart structure while Kimball (Kimball, 1996) defined data warehouse as a bus based data mart structure. Table 2.1 discussed the differences in data warehouse structure between William Inmon and Ralph Kimball. A data warehouse is a read-only data source where end-users are not allowed to change the values or data elements. Inmons (Inmon, 1999) data warehouse architecture strategy is different from Kimballs (Kimball, 1996). Inmons data warehouse model splits data marts as a copy and distributed as an interface between data warehouse and end users. Kimballs views data warehouse as a unions of data marts. The data warehouse is the collections of data marts combine into one central repository. Figure 2.1 illustrates the differences between Inmons and Kimballs data warehouse architecture adopted from (Mailvaganam, 2007). Although Inmon and Kimball have a different design view of data warehouse, they do agree on successful implementation of data warehouse that depends on an effective collection of operational data and validation of data mart. The role of database staging and ETL processes on data are inevitable components in both researchers data warehouse design. Both believed that dependant data warehouse architecture is necessary to fulfil the requirement of enterprise end users in term of preciseness, timing and data relevancy 2.2.1 DATA WAREHOUSE ARCHITECTURE Although data warehouse architecture have wide research scope, and it can be viewed in many perspectives. (Thilini and Hugh, 2005) and (Eckerson, 2003) provide some meaningful way to view and analyse data warehouse architecture. Eckerson states that a successful data warehouse system depends on database staging process which derives data from different integrated Online Transactional Processing (OLTP) system. In this case, ETL process plays a crucial role to make database staging process workable. Survey on factors that influenced selection on data warehouse architecture by (Thilini, 2005) indentifies five data warehouse architecture that are common in use as shown in Table 2.2 Independent Data Marts Independent data marts also known as localized or small scale data warehouse. It is mainly used by departments, divisions of company to provide individual operational databases. This type of data mart is simple yet consists of different form that was derived from multiple design structures from various inconsistent database designs. Thus, it complicates cross data mart analysis. Since every organizational units tend to build their own database which operates as independent data mart (Thilini and Hugh, 2005) cited the work of (Winsberg, 1996) and (Hoss, 2002), it is best used as an ad-hoc data warehouse and also to be use as a prototype before building a real data warehouse. Data Mart Bus Architecture (Kimball, 1996) pioneered the design and architecture of data warehouse with unions of data marts which are known as the bus architecture or virtual data warehouse. Bus architecture allows data marts not only located in one server but it can be also being located on different server. This allows the data warehouse to functions more in virtual mode and combined all data marts and process as one data warehouse. Hub-and-spoke architecture (Inmon, 1999) developed hub and spoke architecture. The hub is the central server taking care of information exchange and the spoke handle data transformation for all regional operation data stores. Hub and spoke mainly focused on building a scalable and maintainable infrastructure for data warehouse. Centralized Data Warehouse Architecture Central data warehouse architecture build based on hub-and-spoke architecture but without the dependent data mart component. This architecture copies and stores heterogeneous operational and external data to a single and consistent data warehouse. This architecture has only one data model which are consistent and complete from all data sources. According to (Inmon, 1999) and (Kimball, 1996), central data warehouse should consist of database staging or known as operational data store as an intermediate stage for operational processing of data integration before transform into the data warehouse. Federated Architecture According to (Hackney, 2000), federated data warehouse is an integration of multiple heterogeneous data marts, database staging or operational data store, combination of analytical application and reporting systems. The concept of federated focus on integrated framework to make data warehouse more reliable. (Jindal, 2004) conclude that federated data warehouse are a practical approach as it focus on higher reliability and provide excellent value. (Thilini and Hugh, 2005) conclude that hub and spoke and centralized data warehouse architectures are similar. Hub and spoke is faster and easier to implement because no data mart are required. For centralized data warehouse architecture scored higher than hub and spoke as for urgency needs for relatively fast implementation approach. In this work, it is very important to identify which data warehouse architecture that is robust and scalable in terms of building and deploying enterprise wide systems. (Laney, 2000), states that selection of appropriate data warehouse architecture must incorporate successful characteristic of various data warehouse model. It is evident that two data warehouse architecture prove to be popular as shown by (Thilini and Hugh, 2005), (Eckerson, 2003) and (Mailvaganam, 2007). First hub-and-spoke proposed by (Inmon, 1999) as it is a data warehouse with dependant data marts and secondly is the data mart bus architecture with dimensional data marts proposed by (Kimball, 1996). The selection of the new proposed model will use hub-and-spoke data warehouse architecture which can be used for MDDB modelling. 2.2.2 DATA WAREHOUSE EXTRACT, TRANSFORM, LOADING Data warehouse architecture process begins with ETL process to ensure the data passes the quality threshold. According to Evin (2001), it is essential to have right dataset. ETL are an important component in data warehouse environment to ensure dataset in the data warehouse are cleansed from various OLTP systems. ETLs are also responsible for running scheduled tasks that extract data from OLTP systems. Typically, a data warehouse is populated with historical information from within a particular organization (Bunger, Colby, Cole, McKenna, Mulagund, and Wilhite, 2001). The complete process descriptions of ETL are discussed in table 2.3. Data warehouse database can be populated with a wide variety of data sources from different locations, thus collecting all the different dataset and storing it in one central location is an extremely challenging task (Calvanese, Giacomo, Lenzerini, Nardi, and Rosati, , 2001). However, ETL processes eliminate the complexity of data population via simplified process as depicts in figure 2.2. The ETL process begins with data extract from operational databases where data cleansing and scrubbing are done, to ensure all datas are validated. Then it is transformed to meet the data warehouse standards before it is loaded into data warehouse. (Zhou et al, 1995) states that during data integration process in data warehouse, ETL can assist in import and export of operational data between heterogeneous data sources using Object linking and embedding database (OLE-DB) based architecture where the data are transform to populate all validated data into data warehouse. In (Kimball, 1996) data warehouse architecture as depicted in figure 2.3 focuses on three important modules, which is the back room presentation server and the front room. ETL processes is implemented in the back room process, where the data staging services in charge of gathering all source systems operational databases to perform extraction of data from source systems from different file format from different systems and platforms. The second step is to run the transformation process to ensure all inconsistency is removed to ensure data integrity. Finally, it is loaded into data marts. The ETL processes are commonly executed from a job control via scheduling task. The presentation server is the data warehouse where data marts are stored and process here. Data stored in star schema consist of dimension and fact tables. This is where data are then process of in the front room where it is access by query services such as reporting tools, desktop tools, OLAP and data mining tools. Although ETL processes prove to be an essential component to ensure data integrity in data warehouse, the issue of complexity and scalability plays important role in deciding types of data warehouse architecture. One way to achieve a scalable, non-complex solution is to adopt a hub-and-spoke architecture for the ETL process. According to Evin (2001), ETL best operates in hub-and-spoke architecture because of its flexibility and efficiency. Centralized data warehouse design can influence the maintenance of full access control of ETL processes. ETL processes in hub and spoke data warehouse architecture is recommended in (Inmon, 1999) and (Kimball, 1996). The hub is the data warehouse after processing data from operational database to staging database and the spoke(s) are the data marts for distributing data. Sherman, R (2005) state that hub-and-spoke approach uses one-to-many interfaces from data warehouse to many data marts. One-to-many are simpler to implement, cost effective in a long run and ensure consistent dimensions. Compared to many-to-many approach it is more complicated and costly. 2.2.3 DATA WAREHOUSE FAILURE AND SUCCESS FACTORS Building a data warehouse is indeed a challenging task as data warehouse project inheriting a unique characteristics that may influence the overall reliability and robustness of data warehouse. These factors can be applied during the analysis, design and implementation phases which will ensure a successful data warehouse system. Section 2.2.3.1 focus on factors that influence data warehouse project failure. Section 2.2.3.2 discusses on the success factors which implementing the correct model to support a successful data warehouse project. 2.2.3.1 DATA WAREHOUSE FAILURE FACTORS (Hayen, Rutashobya, and Vetter, 2007) studies shows that implementing a data warehouse project is costly and risky as a data warehouse project can cost over $1 million in the first year. It is estimated that two-thirds of the effort of setting up the data warehouse projects attempt will fail eventually. (Hayen et al, 2007) cited on the work of (Briggs, 2002) and (Vassiliadis, 2004) noticed three factors for the failure of data warehouse project which is environment, project and technical factors as shown in table 2.4. Environment leads to organization changes in term of business, politics, mergers, takeovers and lack of top management support. These include human error, corporate culture, decision making process and poor change management (Watson, 2004) (Hayen et al, 2007). Poor technical knowledge on the requirements of data definitions and data quality from different organization units may cause data warehouse failure. Incompetent and insufficient knowledge on data integration, poor selection on data warehouse model and data warehouse analysis applications may cause huge failure. In spite of heavy investment on hardware, software and people, poor project management factors may lead data warehouse project failure. For example, assigning a project manager that lacks of knowledge and project experience in data warehouse, may cause impediment of quantifying the return on investment (ROI) and achievement of project triple constraint (cost, scope, time). Data ownership and accessibility is a potential factor that may cause data warehouse project failure. This is considered vulnerable issue within the organization that one must not share or acquire someone else data as this considered losing authority on the data (Vassiliadis, 2004). Thus, it emphasis restriction on any departments to declare total ownership of pure clean and error free data that might cause potential problem on ownership of data rights. 2.2.3.2 DATA WAREHOUSE SUCCESS FACTORS (Hwang M.I., 2007) stress that data warehouse implementations are an important area of research and industrial practices but only few researches made an assessment in the critical success factors for data warehouse implementations. He conducted a survey on six data warehouse researchers (Watson Haley, 1997; Chen et al., 2000; Wixom Watson, 2001; Watson et al., 2001; Hwang Cappel, 2002; Shin, 2003) on the success factors in a data warehouse project. He concluded his survey with a list of successful factors which influenced data warehouse implementation as depicted in figure 2.8. He shows eight implementation factors which will directly affect the six selected success variables The above mentioned data warehouse success factors provide an important guideline for implementing a successful data warehouse projects. (Hwang M.I., 2007) studies shows an integrated selection of various factors such as end user participation, top management support, acquisition of quality source data with profound and well-defined business needs plays crucial role in data warehouse implementation. Beside that, other factors that was highlighted by Hayen R.L. (2007) cited on the work of Briggs (2002) and Vassiliadis (2004), Watson (2004) such as project, environment and technical knowledge also influenced data warehouse implementation. Summary In this work on the new proposed model, hub-and-spoke architecture is use as Central repository service, as many scholars including Inmon, Kimball, Evin, Sherman and Nicola adopt to this data warehouse architecture. This approach allows locating the hub (data warehouse) and spokes (data marts) centrally and can be distributed across local or wide area network depending on business requirement. In designing the new proposed model, the hub-and-spoke architecture clearly identifies six important data warehouse components that a data warehouse should have, which includes ETL, Staging Database or operational database store, Data marts, MDDB, OLAP and data mining end users applications such as Data query, reporting, analysis, statistical tools. However, this process may differ from organization to organization. Depending on the ETL setup, some data warehouse may overwrite old data with new data and in some data warehouse may only maintain history and audit trial of all changes of the data. 2.3 ONLINE ANALYTICAL PROCESSING OLAP Council (1997) define OLAP as a group of decision support system that facilitate fast, consistent and interactive access of information that has been reformulate, transformed and summarized from relational dataset mainly from data warehouse into MDDB which allow optimal data retrieval and for performing trend analysis. According to Chaudhuri (1997), Burdick, D. et al. (2006) and Vassiladis, P. (1999), OLAP is important concept for strategic database analysis. OLAP have the ability to analyze large amount of data for the extraction of valuable information. Analytical development can be of business, education or medical sectors. The technologies of data warehouse, OLAP, and analyzing tools support that ability. OLAP enable discovering pattern and relationship contain in business activity by query tons of data from multiple database source systems at one time (Nigel. P., 2008). Processing database information using OLAP required an OLAP server to organize and transformed and builds MDDB. MDDB are then separated by cubes for client OLAP tools to perform data analysis which aim to discover new pattern relationship between the cubes. Some popular OLAP server software programs include Oracle (C), IBM (C) and Microsoft (C). Madeira (2003) supports the fact that OLAP and data warehouse are complementary technology which blends together. Data warehouse stores and manages data while OLAP transforms data warehouse datasets into strategic information. OLAP function ranges from basic navigation and browsing (often known as slice and dice), to calculations and also serious analysis such as time series and complex modelling. As decision-makers implement more advanced OLAP capabilities, they move from basic data access to creation of information and to discovering of new knowledge. 2.3.4 OLAP ARCHITECTURE In comparison to data warehouse which usually based on relational technology, OLAP uses a multidimensional view to aggregate data to provide rapid access to strategic information for analysis. There are three type of OLAP architecture based on the method in which they store multi-dimensional data and perform analysis operations on that dataset (Nigel, P., 2008). The categories are multidimensional OLAP (MOLAP), relational OLAP (ROLAP) and hybrid OLAP (HOLAP). In MOLAP as depicted in Diagram 2.11, datasets are stored and summarized in a multidimensional cube. The MOLAP architecture can perform faster than ROLAP and HOLAP (C). MOLAP cubes designed and build for rapid data retrieval to enhance efficient slicing and dicing operations. MOLAP can perform complex calculations which have been pre-generated after cube creation. MOLAP processing is restricted to initial cube that was created and are not bound to any additional replication of cube. In ROLAP as depict in Diagram 2.12, data and aggregations are stored in relational database tables to provide the OLAP slicing and dicing functionalities. ROLAP are the slowest among the OLAP flavours. ROLAP relies on data manipulating directly in the relational database to give the manifestation of conventional OLAPs slicing and dicing functionality. Basically, each slicing and dicing action is equivalent to adding a WHERE clause in the SQL statement. (C) ROLAP can manage large amounts of data and ROLAP do not have any limitations for data size. ROLAP can influence the intrinsic functionality in a relational database. ROLAP are slow in performance because each ROLAP activity are essentially a SQL query or multiple SQL queries in the relational database. The query time and number of SQL statements executed measures by its complexity of the SQL statements and can be a bottleneck if the underlying dataset size is large. ROLAP essentially depends on SQL statements generation to query the relational database and do not cater all needs which make ROLAP technology conventionally limited by what SQL functionality can offer. (C) HOLAP as depict in Diagram 2.13, combine the technologies of MOLAP and ROLAP. Data are stored in ROLAP relational database tables and the aggregations are stored in MOLAP cube. HOLAP can drill down from multidimensional cube into the underlying relational database data. To acquire summary type of information, HOLAP leverages cube technology for faster performance. Whereas to retrieve detail type of information, HOLAP can drill down from the cube into the underlying relational data. (C) In OLAP architectures (MOLAP, ROLAP and HOLAP), the datasets are stored in a multidimensional format as it involves the creation of multidimensional blocks called data cubes (Harinarayan, 1996). The cube in OLAP architecture may have three axes (dimensions), or more. Each axis (dimension) represents a logical category of data. One axis may for example represent the geographic location of the data, while others may indicate a state of time or a specific school. Each of the categories, which will be described in the following section, can be broken down into successive levels and it is possible to drill up or down between the levels. Cabibo (1997) states that OLAP partitions are normally stored in an OLAP server, with the relational database frequently stored on a separate server from OLAP server. OLAP server must query across the network whenever it needs to access the relational tables to resolve a query. The impact of querying across the network depends on the performance characteristics of the network itself. Even when the relational database is placed on the same server as OLAP server, inter-process calls and the associated context switching are required to retrieve relational data. With a OLAP partition, calls to the relational database, whether local or over the network, do not occur during querying. 2.3.3 OLAP FUNCTIONALITY OLAP functionality offers dynamic multidimensional analysis supporting end users with analytical activities includes calculations and modelling applied across dimensions, trend analysis over time periods, slicing subsets for on-screen viewing, drilling to deeper levels of records (OLAP Council, 1997) OLAP is implemented in a multi-user client/server environment and provide reliably fast response to queries, in spite of database size and complexity. OLAP facilitate the end user integrate enterprise information through relative, customized viewing, analysis of historical and present data in various what-if data model scenario. This is achieved through use of an OLAP Server as depicted in diagram 2.9. OLAP functionality is provided by an OLAP server. OLAP server design and data structure are optimized for fast information retrieval in any course and flexible calculation and transformation of unprocessed data. The OLAP server may either actually carry out the processed multidimensional information to distribute consistent and fast response times to end users, or it may fill its data structures in real time from relational databases, or offer a choice of both. Essentially, OLAP create information in cube form which allows more composite analysis compares to relational database. OLAP analysis techniques employ slice and dice and drilling methods to segregate data into loads of information depending on given parameters. Slice is identifying a single value for one or more variable which is non-subset of multidimensional array. Whereas dice function is application of slice function on more than two dimensions of multidimensional cubes. Drilling function allows end user to traverse between condensed data to most precise data unit as depict in Diagram 2.10. 2.3.5 MULTIDIMENSIONAL DATABASE SCHEMA The base of every data warehouse system is a relational database build using a dimensional model. Dimensional model consists of fact and dimension tables which are described as star schema or snowflake schema (Kimball, 1999). A schema is a collection of database objects, tables, views and indexes (Inmon, 1996). To understand dimensional data modelling, Table 2.10 defines some of the terms commonly used in this type of modelling: In designing data models for data warehouse, the most commonly used schema types are star schema and snowflake schema. In the star schema design, fact table sits in the middle and is connected to other surrounding dimension tables like a star. A star schema can be simple or complex. A simple star consists of one fact table; a complex star can have more than one fact table. Most data warehouses use a star schema to represent the multidimensional data model. The database consists of a single fact table and a single table for each dimension. Each tuple in the fact table consists of a pointer or foreign key to each of the dimensions that provide its multidimensional coordinates, and stores the numeric measures for those coordinates. A tuple consist of a unit of data extracted from cube in a range of member from one or more dimension tables. (C, http://msdn.microsoft.com/en-us/library/aa216769%28SQL.80%29.aspx). Each dimension table consists of columns that correspond to attributes of the dimension. Diagram 2.14 shows an example of a star schema For Medical Informatics System. Star schemas do not explicitly provide support for attribute hierarchies which are not suitable for architecture such as MOLAP which require lots of hierarchies of dimension tables for efficient drilling of datasets. Snowflake schemas provide a refinement of star schemas where the dimensional hierarchy is explicitly represented by normalizing the dimension tables, as shown in Diagram 2.15. The main advantage of the snowflake schema is the improvement in query performance due to minimized disk storage requirements and joining smaller lookup tables. The main disadvantage of the snowflake schema is the additional maintenance efforts needed due to the increase number of lookup tables. (C) Levene. M (2003) stresses that in addition to the fact and dimension tables, data warehouses store selected summary tables containing pre-aggregated data. In the simplest cases, the pre-aggregated data corresponds to aggregating the fact table on one or more selected dimensions. Such pre-aggregated summary data can be represented in the database in at least two ways. Whether to use star or a snowflake mainly depends on business needs. 2.3.2 OLAP Evaluation As OLAP technology taking prominent place in data warehouse industry, there should be a suitable assessment tool to evaluate it. E.F. Codd not only invented OLAP but also provided a set of procedures which are known as the Twelve Rules for OLAP product ability assessment which include data manipulation, unlimited dimensions and aggregation levels and flexible reporting as shown in Table 2.8 (Codd, 1993): Codd twelve rules of OLAP provide us an essential tool to verify the OLAP functions and OLAP models used are able to produce desired result. Berson, A. (2001) stressed that a good OLAP system should also support a complete database management tools as a utility for integrated centralized tool to permit database management to perform distribution of databases within the enterprise. OLAP ability to perform drilling mechanism within the MDDB allows the functionality of drill down right to the source or root of the detail record level. This implies that OLAP tool permit a smooth changeover from the MDDB to the detail record level of the source relational database. OLAP systems also must support incremental database refreshes. This is an important feature as to prevent stability issues on operations and usability problems when the size of the database increases. 2.3.1 OLTP and OLAP The design of OLAP for multidimensional cube is entirely different compare to OLTP for database. OLTP is implemented into relational database to support daily processing in an organization. OLTP system main function is to capture data into computers. OLTP allow effective data manipulation and storage of data for daily operational resulting in huge quantity of transactional data. Organisations build multiple OLTP systems to handle huge quantities of daily operations transactional data can in short period of time. OLAP is designed for data access and analysis to support managerial user strategic decision making process. OLAP technology focuses on aggregating datasets into multidimensional view without hindering the system performance. According to Han, J. (2001), states OLTP systems as Customer oriented and OLAP is a market oriented. He summarized major differences between OLTP and OLAP system based on 17 key criteria as shown in table 2.7. It is complicated to merge OLAP and OLTP into one centralized database system. The dimensional data design model used in OLAP is much more effective for querying than the relational database query used in OLTP system. OLAP may use one central database as data source and OLTP used different data source from different database sites. The dimensional design of OLAP is not suitable for OLTP system, mainly due to redundancy and the loss of referential integrity of the data. Organization chooses to have two separate information systems, one OLTP and one OLAP system (Poe, V., 1997). We can conclude that the purpose of OLTP systems is to get data into computers, whereas the purpose of OLAP is to get data or information out of computers. 2.4 DATA MINING Many data mining scholars (Fayyad, 1998; Freitas, 2002; Han, J. et. al., 1996; Frawley, 1992) have defined data mining as discovering hidden patterns from historical datasets by using pattern recognition as it involves searching for specific, unknown information in a database. Chung, H. (1999) and Fayyad et al (1996) referred data mining as a step of knowledge discovery in database and it is the process of analyzing data and extracts knowledge from a large database also known as data warehouse (Han, J., 2000) and making it into useful information. Freitas (2002) and Fayyad (1996) have recognized the advantageous tool of data mining for extracting knowledge from a da
